Migrate to Win7 X64 from Win7 X86

Microsoft Windows 7 professional 64-bit
July 29, 2010 at 00:35:08
Specs: Windows 7, Core2 Duo 2.4 GHz, 4.00GB
I am planning to upgrade from Windows 7 32 bit to 64 bit on the same machine. During the migration, I am wanting to install 64 bit on Drive D, and leave the 32 bit instance on Drive C until complete and tested. Once all data and apps have been proven on the 64 bit system I will delete the 32 bit instance completely.

Assuming the harwdare is up to the task, am I able to install the 2 instances side-by-side on separate partitions or will there be a boot issue later on? Will I be able to select between the 32 and 64 bit instances at start-up?

just choose advanced install from the win7 installation and choose d: drive, you can run both 32 and 64 bit systems in dual/tri/quad bootups

The second install of your Win 7 will be the default choice. You can choose either OS within 30 seconds at bootup. When you want to delete one of the OSs, you can either use bcdedit.exe or EasyBCD which you can download from HERE.

I doubt you will find any value to this task unless you have more than 4G of ram or you have some advanced program that requires 64 bit.
